(ET) More inverter stuff.....

["Elie, Larry (L.D.)" <lelie ford com>]

OK, I thought I might as well be complete on the 'cheap' inverters.

I e-mailed again, asking about combined inverter/chargers (I don't 
much care for the ET charger) and the reply is below.  First another 
thought.

Now I have been thinking.  I may yet design an inverter for this 
puppy.  A 'cheap' power amplifier driven by an astable multivibrator 
(if you don't know what that means, don't worry) is very easy to 
do BUT the frequency would be high unless you use expensive caps.  
It would not clock 60 Hz at all, but this could be done with the 
transformer of the charger of the ET with only a few modifications.  
Cost would be in the tens of dollars.  However, I am thinking about 
doing a clocked design and doing it right.  Essentially the only 
part of the charger you would use would be the transformer.  I think 
I could upgrade the charger while I am at it.  This would cost more.  
It might cost as much as the ones listed below.  It would be fairly  
wimpy; Bill Gunn once told me the charger could put out 20 Amps for 
a while (I haven't measured it-- has anyone else?) but that only 
works out to something like 720 watts.  If that's continuous it might 
do, but if it's intermittent it isn't that good.  Compare it with the 
ones below.  I'm going to try and model the designs.  I will keep the 
list posted.

Thank you so much.  Final question; Do you have any 36V combined
inverter/battery 
chargers?  If so, any other info on them such as price would be welcome.
